  • Patent number: 5627510
    Abstract: A vehicular safety distance alarm system for monitoring a travelling distance between a source vehicle and a target vehicle and activating an alarm when a predetermined safety distance defined between the two for a given speed is compromised comprising a distance measurement mechanism coupled to a source vehicle for determining and transmitting a distance signal representing a travelling distance between the source vehicle and a remote target vehicle; a selection mechanism coupled to the source vehicle for allowing a driver to select a desired range of safety distances expressed as a function of source vehicle velocity and a set time to reach a target vehicle; an alarm signal generation mechanism coupled to the distance measurement mechanism and selection mechanism for comparing the distance signal to a safety distance at a given source vehicle velocity and transmitting an alarm signal when the safety distance is compromised; and an alarm mechanism coupled to the alarm signal generation mechanism for providin
